Abstract (en)
[origin: EP2628600A1] An image forming apparatus includes: conveying means for conveying a recording medium; a liquid droplet ejection head configured to eject liquid droplets onto the recording medium; emission means (230) for emitting a detection beam (L1), which is used for detecting the recording medium, and a reference beam (L2), which is farther from a conveying surface of the conveying means than the detection beam (L1), along the conveying surface of the conveying means, the emission means being provided upstream of the liquid droplet ejection head in a conveying direction of the recording medium; light receiving means (240) for receiving the detection beam and the reference beam; and floating determination means (260) for determining whether the recording medium is floated, based upon a magnitude of a difference between an amount of light of the detection beam (L1) received by the light receiving means and an amount of light of the reference beam (L2)received by the light receiving means.
